HORSESHOE ATTACHMENT.

Specification of Letters Patent.

Patented May 17, 1910.

Application filed November 8, 1909. Serial No. 526,861.

To all whom it may concern:

Be it known that I, HERMANN Horn, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Horseshoe Attachments, of which the following isa full, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention has relation to improvements in horse-shoe attachments; andit consists in the novel details of construction more fully set forth inthe specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a hoof showing the shoeand its attachment in longitudinal middle vertical section; Fig. 2 is atop plan of the shoe with the attachment in place; Fig. 3 is a bottomplan of the same; Fig. 4: is a vertical cross section 011 the line 4L4of Fig. 2; Fig. 5 is a vertical cross-section on the line 5 5 of Fig. 2;and Fig. 6 is a sectional detail on the line 6-6 of Fig. 2.

The object of my invention is to provide a call: attachment for horseshoes which may be temporarily secured to the ordinary shoe on specialoccasions, as for example where the animal is to travel over ice, snowand slippery roads, the attachment being readily removed from the shoewhen the latter can be utilized for general service.

The invention resides in structural details the advantages of which willbe apparent from a description thereof which is as folows:

Referring to the drawings, S, represents an ordinary shoe secured to thehoof H of the animal as usual, the shoe being provided with a toe calk tand heel calks h, h.

Mounted respectively on the screw threaded and smooth portions of anadjusting stem 1 are a relatively adjustable rear wedge or block 2 andan abutment or front block 3, each block being recessed or cut away to asufficient de th to afford supporting ledges a, a, a, a, respectivelyfor the shoe S, the depth of the recesses being such as to bring theupper surface of the shoe flush with the corresponding surfaces of theblocks, and thus afford a maximum supporting surface for the hoof H. Thebottom faces of the blocks 2 and 3 are provided respectively with calks0 which are removable for purposes of renewal, being secured by screwsl. The front vertical wall or edge e of the block 3 is straight so as toafford a better bearin for the front or toe calk 25 of the shoe S,FFigs. 2, 3), when the attachment is in place. The outer or rear end ofthe stem 1 terminates in a square or polygonal head 5 for receiving thesocket of a wrench or key (not shown) by which the stem may be rotated.The forward end of the stem terminates within the block 3 in an annulargroove 6 for the reception of the inner end of a securing screw 7 which,while it permits the stem to freely rotate within the block or abutment3, prevents its accidental withdrawal.

In applying the attachment, the same is placed with the supportingledges a, a of the respective blocks 2, 3 against the bottom of theshoe, the toe calk t engaging the front edge e of the block or abutment3, and the curvature of the recessed portion (follow ing as it does thecurvature of the inner edge of the shoe) abutting against the inner edgeof the shoe opposite the toe (Figs. 2, 3). The operator then imparts thenecessary rotation to the stem 1, whereby the block or wedge 2 is forcedoutwardly and rearwardly, the sides of the block wedging themselvesfirmly between the converging edges of the sides of the shoe, by whichtime the heel calks h, h, are in substantial engagement with the rearstraight wall of the wedge, thus preventing the accumulation of dirtbetween the engaging surfaces. In the wedging of the block 2 between thesides of the shoe, the relatively stationary block 3 serves in thenature of an abutment against which the stem 1 may brace itself. Oncethe block 2 is thoroughly wedged in place, the attachment remains on theshoe until loosened and detached therefrom. This removablecalkattachment is serviceable especially in winter when it is notdesirable to remove the shoe S for the special sharpening of its calksto travel over slippery surfaces.

Having described my invention, what I claim is 1. In combination with ahorseshoe having opposite plane parallel faces, a calk-attachmentcomprising a front and rear block having ledges for the support of theshoe, and recessed to bring the upper surfaces of the blocks flush withand in the plane of the corresponding surface of the shoe, the frontblock having a curved vertical wall abutting against the inner curvededge of the shoe opposite the toe, and the rear block having taperingsides adapted to wedge against the inner edges of the sides of the shoe,a screwstem connecting the blocks, and adapted to advance the Wedge orrear block to proper position to effect the necessary engagement Withthe sides of the shoe, substantially as set forth.

2, In combination With a horse-shoe having opposite plane parallelfaces, a calk-attachment comprising a front and rear block having ledgesfor the support of the shoe, and recessed to bring the upper faces ofthe blocks flush with and in the plane of the corresponding face of theshoe, the front block having a curved vertical Wall abutting against theinner curved edge of the shoe opposite the toe, and a straight edge orWall for engaging the toe-call: of the shoe, and the rear-blook havingvertlcal tapering Walls for wedging against the inner edges of the sidesof the shoe, an adjusting screw operating loosely in the front block,and having a screw-threaded portion for adjusting the position of theWedge or rear block, the rear terminal of the stem having means for theapplication of a Wrench or equivalent tool, substantially as set forth.

In testimony whereof I aflix my signature, in presence of two Witnesses.
